I've been looking through the old posts and I know this gets asked a lot, but I just want to be sure on what I should do. I really don't want to harm the chicks that are hatching. The eggs have started pipping today and I just saw the mites today. Ida is in good feather except for a couple spots on her head that I assumed the roos had pulled feathers out of when they mounted her and the stupid little buggars and crawling around her face and head. At this point can I sevin dust her or should I wait until everyone hatches and I can move them, change bedding, and dust everybody and everything? I have food grade DE, but the general consensus seems to be negative regarding it's use as an 'insecticide' per-sae.
